Choose the sales leadership response for the next six months

When a VP Sales leaves, the business does not get a neutral pause. Forecast quality degrades, managers make local decisions, hiring slows and strategic deals lose executive attention.

Start with the next six months of operating risk, not a preference for employment type. An interim VP Sales is a time-bound operator with a defined mandate. A permanent hire is a long-term leadership appointment. Neither is automatically cheaper or better.

Write the decision memo before opening a search: what must be different by the review date, which decisions are waiting, and what authority is required to make them. If the answer is “we need a durable builder for an established strategy”, hire permanently. If the answer is “we have a live gap and need the operating system stabilised now”, interim leadership may be the more responsible bridge.

Operator example: a six-month leadership gap

Imagine a 35-person software sales team whose VP leaves during a quarter with open enterprise renewals and three manager vacancies. The interim brief might require a weekly forecast, manager coverage, a hiring decision on each vacancy and a documented permanent-role profile. Those are outputs and decision rights. “Improve sales” is not a mandate. The example is illustrative; use the company’s own renewal calendar, pipeline and leadership risks to set the review date.

When an interim sales leader is right

Four situations that favour interim

A sudden exit. The team needs a decision-maker while a permanent search runs. The interim should own the forecast, manager rhythm and priority deals rather than merely attend leadership meetings.

A new market entry. Sales leadership may be needed for a market test before a permanent country structure is justified. The mandate should define the evidence that supports continuation, change or stop.

A pre-raise fix. The company needs a credible pipeline view, forecast rhythm and leadership assessment before fundraising. The interim can document the machine without pretending that a short assignment proves long-term growth.

A turnaround. The problem is visible and the company needs diagnosis and intervention before it knows which permanent profile to hire.

When to hold out for permanent

Hire permanently when the role is central to a durable market strategy, the leadership team can support a full search and the company is ready to give the incoming VP a stable mandate. A permanent leader is also the beter fit when the work is long-term culture building, succession or multi-year team design rather than a defined intervention.

Do not use an interim to avoid a strategic decision. Write the decision down, assign an owner and set the date to revisit it.

Interim vs. fractional vs. permanent: the actual differences

Dimension	Interim	Fractional	Permanent
Commitment	Full ownership for a defined mandate	Part-time leadership on an agreed schedule	Ongoing employment
Cost basis	Contracted time or deliverables	Recurring part-time structure	Compensation and employment cost
Authority	Must be explicit	Often narrower	Built into the role
Best fit	Gap, turnaround, launch or transition	Coaching or oversight	Durable strategy and team building

The label matters less than the agreement. A fractional VP with no authority is an adviser. An interim with authority over forecast, managers and hiring is an operator. Put availability, decision rights, reporting line and handover obligations in writing.

What each option really costs

Why day rate versus salary is the wrong comparison

Compare the full decision. For an interim, include fee, onboarding, travel, access, internal sponsor time and transition. For a permanent leader, include compensation, variable pay, benefits, employer costs, search and assessment, onboarding and the cost of a failed appointment.

Do not fill a spreadsheet with a day rate or salary band unless it comes from a named, relevant benchmark. The useful comparison is the strucutre: what is paid, when it starts, what risk it removes and what risk remains.

The fully loaded permanent cost

Build a line-by-line estimate: compensation, employer costs, search, relocation or travel, leadership time, onboarding and the team’s cost while the role is unsettled. Add sensitivity for a delayed start and a failed appointment. Keep the assumptions separate from observed internal costs.

The vacancy cost

List the decisions waiting for the VP: forecast calls, manager coaching, territories, hiring, pricing and strategic deals. Assign each an interim owner and a date. Vacancy cost is not only missed revenue; it is slower decisions and the risk that the team learns the wrong habits.

Compare the cost of intervention with the cost of leaving the decision unowned for another month. This does not produce a universal answer, but it forces the business to price delay rather than treating it as free.

What a good interim VP Sales does in the first 90 days

Days 1–30: diagnosis

Establish how stages are defined, whether CRM data matches reality, where deals stall, which managers can run their teams and what the forecast has historically meant. Meet the team, inspect live deals and publish a short diagnosis with decisions required.

The first-month output should include a forecast definition, a list of material pipeline risks, a manager capability view, open hiring decisions and the minimum report set. Do not spend the month producing a presentation that does not change an owner or decision.

Days 31–60: intervention

Set a review cadence, remove duplicate reporting, define what commit means, coach managers on deal inspection and clear blockers. Test the requirements for the permanent role: builder, turnaround specialist, market opener or operating leader.

Make the intervention visible. Managers should know what they own, what evidence is expected in the forecast and which escalations need the sponsor. The interim should be able to point to changed decisions, not just increased meeting volume.

Days 61–90: build

Document definitions, reports, meeting decisions, hiring priorities and risks. A permanent candidate should see the real mandate, not an idealised job description. The handover should include the forecast history, pipeline risks, team assessment, open decisions and a calendar of recurring operating reviews.

How to measure whether the interim is working

Agree measures before the interim starts. Otherwise the assignment is judged by charisma, meeting volume or a single deal. Inspect whether:

• forecast categories have written definitions and owners;
• pipeline reports reconcile with CRM fields;
• managers run consistent deal and coaching reviews;
• the capability and hiring plan is documented;
• diagnosis blockers have decisions; and
• the handover pack is usable by a permanent leader.

Set a review date for each measure. If a measure cannot move within the mandate, name the dependency rather than blaming the operator for a decision they cannot make.

Planning the handover to a permanent leader from day one

Name the end condition: permanent hire starts, market test ends or the mandate is extended. Create a handover document with forecast, pipeline risks, team assessment, hiring plan, definitions, calendar and unresolved decisions.

The interim should not make the business dependent on them. Before handover, verify that the system and team can operate without the interim. Use the sales competency model to assess the permanent profile. Connect the mandate to the B2B sales plan, project experience and a sales leadership assessment.

EMEA specifics: contracting, notice periods and works councils

Confirm contractor status, confidentiality, authority to manage employees, data access, travel, tax treatment and termination terms with qualified advisers. In Germany and other EMEA markets, ask your counsel how notice periods, employee representation and works-council processes affect the permanent timeline and the interim’s remit. The answer depends on the country, employment structure and proposed change; it is not a generic article claim.

Do not promise authority the contract or local process cannot support. Put reporting lines, decision rights and the relationship with the founder or CRO in writing.

For a broader management framework, see the Harvard Business Review Sales Management Handbook. Its scope is wider than interim leadership, but its treatment of recruiting, development, analytics and change supports the same operating principle: define the management system and decision rights rather than relying on a title.

A practical mandate document

Write the interim brief before you speak to candidates. It should answer:

• What business problem must be different at the end?
• Which decisions can the interim make without additional approval?
• Which people report to them, formally or operationally?
• Which reports and meetings do they own?
• What must be documented for handover?
• What would make the company extend, end or change the mandate?

Add a first-week access list: CRM, forecast history, compensation plan, hiring pipeline, customer context and the calendar of existing reviews. Delayed access creates a delayed diagnosis and makes the first month look more active than useful.

The founder’s role

The founder or CRO should be available for fast decisions but should not run the interim’s function by proxy. Agree an escalation route, a weekly sponsor check-in and the decisions that require board visibility. Tell managers what the interim owns and what remains with the founder. This protects authority and prevents the team from waiting for the old reporting line to reappear.
